Taking Advantage of New Progressive Lens Designs
Have you noticed that your computer and reading material are not as clear as they used to be? Do you feel like overnight you have lost the ability to focus on reading material up close? If so you may be suffering from a normal aging process known as presbyopia. This condition refers to a loss of the ability to focus on objects at a near distance that usually occurs around the age of forty when the lens in the middle of the eye has become less flexible.
The best technology for overcoming this condition in eyeglasses is known as a progressive lens. Progressive lenses are true multifocal lenses that provide a seamless progression of many lens powers for all viewing distances.
With progressive lenses, you can look up to see clearly across the room during an office presentation or when driving. You can also look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably.
A corridor of optimum vision runs vertically down each progressive lens. Your eye care practitioner will take careful measurements of your eyes and eyeglass frame in order to place the corridor in just the right location so your eyes can naturally access the various powers within the lens for comfortable viewing at all distances.
Progressive lenses also enable you to avoid the annoying image jump phenomenon that occurs with lined bifocals.
Thanks to today's modern progressive lenses it is also easier than ever to adapt to these lenses.
A recent exciting improvement in progressive lens technology has come in the technology of Free Form Progressive Lenses. Free Form is a computer-aided design and manufacturing process that allows for larger intermediate and near visual field areas when looking at your computer and reading material. This makes the lenses much easier to adapt to and adds to their overall clarity and reduced distortion thanks to a reduction of optical aberration level.
If your eyes are feeling tired at the end of the day and you are stretching things away from you so that you can read them, then this new progressive lens design could help you see more clearly at comfortably at all distances.
